I just happened to stumble across your post whilst googling to see if anyone else had lost the same amount of weight as I have in as short a time.
Here is my story, in case it helps motivate you (or anyone else)
I weighed 17 stone 7 (= 248 lbs)
I was having takeaways 3 or 4 times a week, and walking around with untreated very high blood pressure.
On the 18th April this year (good Friday) I was rushed to hospital with a nose bleed I couldn't stop. The whole bathroom looked like a murder scene.
After a few days in hosp, and being put on medication for high blood pressure, I said 'no more'
I now eat only salads for dinner, or weighed out amounts of pasta 125g with onions, garlic and mixed peppers. and a small amount of cereal for breakfast, and fruit and carrots for snacks.
I was told to not do any strenuous exercise until seeing the dr (after blood tests come back next week)
Just with healthy eating, I am now 15 stone 11 = (211.5 lbs)
In just under a month, I have lost close to 2 stone.
My motivation is:-
I never want a repeat of that nosebleed, and I also want to be able to get off blood pressure medication.
My point is, if you want to badly enough, you can lose the weight. Just don't wait until you're forced into doing so!
